INSTALLING THE TYPE-5 PSU.
The Type 5 PSU is used with the B, L and N series SIUs when battery backup
is required. The Type 5 PSU consists of a PSU and battery charger with
standby battery.
STEP PROCEDURE
1. PSU (Type 5) Positioning and Securing
1. Confirm the position of the Type-5 PSU, allow for adequate ventilation and
service access.
2. Note: The life of the battery within the Type-5 PSU will be increased in a
low temperature, but standby time is improved in a warm environment.
Ideally the location should be cool, as the electronics within the unit will
keep it warm enough to ensure a good standby period.
3. Install the Type 5 PSU within 2 metres of an AC power point and 1 metre of
the SIU.
4. Remove the PSU front cover. Offer the PSU up into position and mark the
three fixing positions onto the wall. The PSU should be fitted with the
battery at the top and the mains input connector at the bottom. (See Figure
28).
5. Drill the 3 holes, 8mm. Diameter to a depth of 50mm. (use a depth gauge)
and then fit the FUB x 50mm Wall Plugs (Part No 128-0000-123) provided.
6. Secure the PSU squarely in position using the No 8 x 50mm screws (Part
No 174-0815-002) and cup washers (Part No 192-0080-230) provided.
7. Install the batteries.
Note: Do not connect the batteries until instructed to do so at the
commissioning stage.
